A simple experiment to understand why any external modification or perturbation or modification around an electrical field may matter and in some cases be audible as a kind of filters:
Put a 200 grams piece of quartz on your amplifier, then try with a piece of shungite of the same size... Go from one to the other and listen the difference ; it will be a slight degradation or an improvement , if it is neither of the two try and put them together,...
if your amplifier is on the warm side of thing , the quartz may help it..
If your amplifier is on the cold side the shungite may help it...
If your amp is more balanced the two together may also did something helpful...
In any case the goal is to hear a "change" for the worst or the better and then you will know how the world is not as described in your manuals ...
A varied mix of some minerals do marvel for my Sansui alpha who sound as a tube amplifier to my ears : more fluid and no trace of dryness or shrill or anything making it a S.S. design ... the sound is meatier and i modify it at will... It is like using different cables to my ears...Usually i keep my recipe without changing it because there is more no need to balance it further ...
No sarcasms by empty head will be needed when someone dare to suggest a simple experiment a 4 years old can do... 😊
